요약Robots are increasingly being considered for different manufacturing processing applications. Completing the process efficiently and successfully requires using the right process parameters. Under traditional practices, the responsibility of determining and implementing the right process parameters into the robots has largely been done by human operators. This approach, although reliable, presents drawbacks with its time-consuming nature and associated costs. Instead, we want to facilitate an AI-driven experimental design approach for learning manufacturing tasks using robots. AI-driven experimental design will enable robots to learn from and adapt to the outcomes of previous experiments for determining process parameters to use in further experiments. Robots can try different values of process parameters, evaluate the task performance, and incorporate insights from these evaluations to guide subsequent experiments. Robots can continuously enhance task performance and update process parameter models through this iterative learning approach.The first contribution of this dissertation is to develop and implement an adaptive experimental design for learning tasks characterized by constant process parameter models. Since the process parameter models are constant, the sets of process parameters that ensure efficient and successful task execution can be determined and employed. The AI-driven experimental design integrates aspects of feasibility biased sampling, surrogate model construction, and heuristic-driven optimization. The practical implementation of this approach is demonstrated within the context of a robotic sanding application.The second contribution of this dissertation is building a framework to learn tasks characterized by spatially varying process parameter models through AI-driven experimental design. Compared to models utilizing constant process parameters, those involving spatially varying process parameters are more complex and challenging to learn. The adaptive experimental design presented in this chapter utilizes a combination of initial parameter exploration, surrogate modeling, region sequencing policy selection, and process parameter selection policy. The applied execution of this method is showcased in contact-based robotic finishing tasks. Through the computational simulations and physical experiments of the robotic sanding case study, we demonstrate the successful implementation of our approach.The third contribution of this dissertation is to develop and implement a learning approach for robotic processing applications characterized by temporally varying process parameter models. We implement our approach to direct ink writing applications, where the issue of ink drying is prevalent over time. To account for the issue of ink drying, it becomes necessary to adjust process parameters, such as tool velocity or pressure, accordingly for each temporal phase of the processing. By making temporal adjustments of parameters, we successfully maximize the achievable print length without any constraint violations of the process.The final contribution of this dissertation is developing a sequential decision making approach to learn process parameters by conducting experiments on sacrificial objects. When there is a risk of damaging target objects (objects of interest), experimenting on sacrificial objects is a viable strategy to ensure the safety of the target objects. However, excessive utilization of sacrificial objects could increase the associated costs. Using an appropriate quantity of sacrificial objects is important to complete the task efficiently and safely with the minimum task completion costs. To find the right quantity of sacrificial objects and determine the process parameter to use, we utilize an AI-driven experimental design using a sequential decision making approach. The AI-driven experimental design approach encapsulates aspects of look-ahead search, surrogate modeling, and a policy for process parameter selection. The proposed method is implemented and demonstrated on the robotic spray painting application.
